Description
- The present invention refers to a quick-connection hydraulic coupling joint aimed in particular to connect elements of machine tools or excavation, demolition or earth-mover machines, for example to connect a tool to an handling fixture, such as the articulated arm of an excavator, or the like.
- Currently, hydraulic coupling joints which are usually employed in the above mentioned applications are of the type with front coupling: this implies that the detachment force of such joints, generated by the internal pressure of the working fluid (working pressure), tries to move away-detach the male/female components of the joints which, consequently, must be equipped with adequate and sturdy fastening members which keep them connected.
- This means that, if such components must be jointed or disjointed under pressure, they create difficulties when manoeuvring, especially in manual operations, generating foces which can be managed with difficulty: it must be noted, for example, that, for a ¾-inch joint at the working pressure of 200 bar, generally a detachment force over 1200 Kg is obtained.
- Documents
EP-A1-1 566 490 ,EP-A1-2 230 435 andWO-A1-2008/071012 disclose hydraulic joints according to the preamble ofClaim 1. - Therefore, object of the present invention is solving the above prior art problems, by providing a quick-connection hydraulic coupling joint in which the detachment force of the components of such joint generated by the pressurised working fluid remains inside the joint itself and generates a minimum moving-away resulting force, which can be easily counteracted by weak retention systems, since the force to be counteracted is minimum.
- Another object of the present invention is providing a quick-connection hydraulic coupling joint which can be easily made with multiple channels, due to the fact that, even if the forces are multiplied for every connection, they do not generate detachment effects of the components of the joint itself.
- Moreover, an object of the present invention is providing a quick-connection hydraulic coupling joint which has much smaller sizes with respect to what is proposed by the prior art, not having to require the insertion of sturdy and bulky retention systems.
- The above and other objects and advantages of the invention, as will appear from the following description, are obtained with an hydraulic coupling joint as claimed in
claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims. - It is intended that all enclosed claims are an integral part of the present description.
- It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) can be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.
- The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed claims, in which:
-
Figure 1 shows a side sectional view of a preferred embodiment of the quick-connection hydraulic coupling joint according to the present invention in its disconnection position; -
Figure 2 shows a side sectional view of the quick-connection hydraulic coupling joint ofFigure 1 in its connection position; -
Figure 3 shows a front sectional view of a preferred embodiment of a female connection component of the quick-connection hydraulic coupling joint according to the present invention; -
Figure 4 shows a front sectional view of a preferred embodiment of a male connection component of the quick-connection hydraulic coupling joint according to the present invention; -
Figure 5 shows another preferred embodiment of the quick-connection hydraulic coupling joint according to the present invention in an opened configuration; and -
Figure 6 shows the quick-connection hydraulic coupling joint ofFigure 5 in a closed configuration. - With reference to the Figures, it is possible to note that the quick-connection
hydraulic coupling joint 1 according to the present invention comprises at least one female connection component 1a and at least onemale connection component 1b, such female connection component 1a being equipped with at least onefirst passage duct 3a of at least one pressurised working fluid (for example oil) connected with at least one first passage opening 5a of such fluid, suchmale connection component 1b being equipped with at least onesecond passage duct 3b of at least such pressurised working fluid connected with at least one second passage opening 5b of such fluid, suchmale connection component 1b being equipped with at least oneprojecting connection element 7b on the surface of which such second passage opening 5b is arranged, and such female connection component 1a being equipped with acorresponding seat 7a on the surface of which such first passage opening 5a is arranged and is adapted to house therein suchprojecting connection element 7b when thejoint 1 according to the present invention is in its connection position (like the one, for example, shown inFigure 2 , obtained taking the female connection component 1a and themale connection component 1b one against the other according to the direction of arrows C ofFigure 1 , by inserting theprojecting connection element 7b inside theseat 7a), to take such first passage opening 5a next to and in fluidic connection with such second passage opening 5b in order to share a common flow axis F-F of such working fluid passing through suchfirst passage duct 3a, such first passage opening 5a, suchsecond passage duct 3b and such second passage opening 5b (for example, along the flow trajectories roughly designated with dotted lines inFigure 2 ), or vice versa. - Preferably, such
projecting connection element 7b has a section substantially shaped as a wedge or, as shown in the Figures, as an isosceles trapezoid rotated by 90°,such seat 7a consequently having a corresponding shape:such passage openings projecting connection element 7b and ofsuch seat 7a. - Preferably, between such first passage opening 5a and such second passage opening, at least one sealing
element 9 is interposed, still more preferably composed of at least one gasket of an OR-ring type. - According to the invention, when such female connection component 1a and such
male connection component 1b are in their connection position, they share a virtual, front connection interface plane P subtending with such flow axis F-F an angle α ≠ 90°, namely α << 90°, such angle α being preferably included between 5° and 15°, and still more preferably substantially equal to 10°: in such a way, it can be noted fromFigure 2 that the vector sum of the forces, respectively F1 and F2, generated by the pressurised working fluid passing through suchfirst passage duct 3a, such first passage opening 5a, suchsecond passage duct 3b and such second passage opening 5b are wholly counteracted by the walls defining theseat 7a of the female connection component 1a and generate a component R of the resulting force orthogonal with the virtual interface plane P, which tends to separate the female connection component 1a from themale connection component 1b, having a value substantially lower than the value of the forces F1 and F2, and thereby capable of being easily counteracted even only through the friction generated in the contact of the external surfaces of theprojecting connection element 7b with the internal surfaces of thecorresponding seat 7a inside whith it is inserted and facilitating, at the same time, the voluntary detachment operations ofsuch components 1a, 1b of thejoint 1 according to the present invention. - Preferably, such first passage opening 5a is equipped with first opening/closing means 11a of such first opening 5a and such second passage opening 5b is equipped with second opening/closing means 11b of such second opening 5b in such way as to allow/prevent the passage of the working fluid through
such openings - In particular, such second opening/closing means 11b comprise at least one
second closing plug 13b spontaneoulsy taken to close (such as shown, for example, in particular inFigure 1 ) of the respective second passage opening 5b by at least one respective secondelastic means 15b, preferably composed of at least one coild spring coaxial with the flow axis F-F of the working fluid. - Such first opening/closing means 11a comprise at least one
first closing plug 13a spontaneously taken to close the respective first passage opening 5a by at least one respective firstelastic means 15a, also preferably composed of at least one coil spring coaxial with the flow axis F-F of the working fluid. Moreover, suchfirst closing plug 13a is integral with at least one end of abush 17a axially sliding along such flow axis F-F, on an opposite end ofsuch bush 17a acting under pressure on such firstelastic means 15a : insidesuch bush 17a, at least one thrustingelement 19a is in turn axially sliding along such flow axis F-F, such thrustingelement 19a operatively cooperating with suchsecond closing plug 13b to take this latter one from its closing position of the second opening 5b to its opening position of such opening 5b. - In particular,
such bush 17a and such thrustingelement 19a comprise at least one seat for inserting theenlarging end 21a of at least oneenlarging element 23a, such seats being shaped in such a way that, when suchenlarging end 21a is pushed (for example along the direction shown by arrow D inFigure 2 when the female connection component 1a and themale connection component 1b are pushed one against the other along the direction of arrows C inFigure 1 inserting theprojecting connection element 7b inside theseat 7a) inside such seats, for example through a suitablesliding duct 25a, thebush 17a is progressively pushed to compress the firstelastic means 15a, taking thefirst closing plug 13a integral therewith to free the first passage opening 5a; in parallel, when suchenlarging end 21a is pushed inside such seat, thethrusting element 19a is progressively pushed against thesecond closing plug 13b compressing the second elastic means 15b and freeing the second passage opening 5a: once thepassage openings first passage duct 3a, such first passage opening 5a, suchsecond passage duct 3b and such second passage opening 5b. Obviously, by proceeding in reverse with respect to what is described above, namely eliminating the pressure in the working fluid, moving the female connection component 1a far from themale connection component 1b (for example along an opposite direction to the one shown by arrows C inFigure 1 ), and extracting theprojecting connection element 7b from theseat 7a, theenlarging end 21a is in turn extracted from the seats of thebush 17a and the thrusting element 19°, allowing the first 15a and the second elastic means 15b to take back therespective closing plugs respective passage openings - The above described opening/closing means 11b, 11b thereby allow automatically opening and closing the related passage opening 5a, 5b during the connection and disconnection of the
joint 1 according to the present invention, to adjust the fluid flow evne under pressure and to guarantee the closure of theopenings second component 1b. - Obviously, it is also possible to automatise the connection/disconnection operations of the
joint 1 according to the present invention, for example through suitable hydraulic cylinders, lever/cam type kinematisms or other systems suitable for this purpose. - Moreover, as it is possible to note in particular in
Figures 3 and4 , it is possibile to provide that thejoint 1 according to the present invention is, depending on specific functional needs, of the type with multiple channels comprising at least onefemale connection component 100a with multiple channels and at least onemale connection component 100b with multiple channels, such firstfemale connection component 100a with multiple channels comprising two or more of such female connection components 1a as described above, arranged in parallel, and suchmale connection component 100b with multiple channels comprising two or more (preferably the same number) of suchmale connection components 1b as described above, also arranged in parallel:Figures 3 and4 show as an example a joint according to the present invention composed of afemale connection component 100a with multiple channels and of amale connection component 100b with multiple channels, each one of which respectively composed of four of such female 1a and male 1b connection componenta. -
Figures 5 and6 show another preferred embodiment of the quick-connection hydraulic coupling joint of the present invention, respectively in an open and closed configuration. - The major difference with respect to the previously described hydraulic coupling joint is that the first and
second closing plugs respective passage openings - Moreover, the first and
second closing plugs - The
first closing plug 13a is connected to afirst arm 30a rotatingly hinged at oneend 33a to asecond arm 32a, in turn fixedly hinged at anotherend 31a to the female connection component 1a, thefirst arm 30a being further rotatingly hinged at anotherend 34a to afirst driving rod 35a adapted to slide inside the female connection component 1a, thefirst driving rod 35a being adapted to drive thefirst closing plug 13a from a closing position to an opening position of the first passage opening 5a when pushed by the female connection component 1a and abutted against a fixedabutment wall 50, thefirst driving rod 35a being further adapted to return to its rest position, where thefirst closing plug 13a closes the first passage opening 5a by means of elastic means (not shown, for example one or more springs), when thehydraulic coupling joint 1 must be opened. - Similarly, the
second closing plug 13b is connected to athird arm 30b rotatingly hinged at oneend 33b to afourth arm 32b, in turn fixedly hinged at anotherend 31b to themale connection component 1b, thethird arm 30b being further rotatingly hinged at anotherend 34b to asecond driving rod 35b adapted to slide inside themale connection component 1b, thesecond driving rod 35b being adapted to drive thesecond closing plug 13b from a closing position to an opening position of the second passage opening 5b when pushed by themale connection component 1b and abutted against the fixedabutment wall 50, thesecond driving rod 35b being further adapted to return to its rest position, where thesecond closing plug 13b closes the second passage opening 5b by means of elastic means (not shown, for example one or more springs), when thehydraulic coupling joint 1 must be opened. - With the above arrangement, it is clear that the opening and closing positions of the first and
second passage openings - starting from an opened position of the hydraulic coupling joint 1 (like the one in
Figure 5 ), firstly the female connection component 1a is pushed over themale connection component 1b which enters inside it; - when the male and
female connection components 1a, 1b are mutually coupled, they are together pushed towards the fixedabutment wall 50, and their respective first andsecond driving rods abutment wall 50 and are pushed by this latter one in order to actuate the various first, second, third andfourth arms second closing plugs second passage openings female connection components 1a, 1b are already coupled and assembled together, thereby preventing oil leaks and oil pressure drops; - on the contrary, when the
hydraulic coupling joint 1 must be opened, firstly the first andsecond driving rods abutment wall 50 and are pushed by their respective elastic means to their rest and closing positions, in order to actuate the various first, second, third andfourth arms second closing plugs second passage openings - only when the first and
second passage openings male connection component 1b, again without any problem of oil leak or pressure.
